RAISING BEAM-SCALE.

Specification of Letters Patent.

Patented June 18, 1912.

Application filed December 4, 1911. Serial No. 663,806.

To all whom it may concern Be itknown that I, HARRY SCHNEIDER, a

' citizen of the United States, and resident of the city of New York,borough of Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful Tmproveinents in Raising Beam-Scales, ofwhich the following is a specification.

This invention relates to a weighing device or scale of the raising beamtype and has for its object the provision of a simple and novelconstruction in which the platform of the scale normally rests upon afixed support while the article or articles to be weighed are placed inposition thereon. The platform is suspended from a scale beam and meansare provided for raising the scale beam and platform, together with thearticles to be weighed.

One of the numerous objects of the invention is to provide a means foradjusting the position of the articles to be weighed upon the platformrelative to the point of suspension thereof so that the same will bebalanced and a more accurate weighing secured.

In carrying out my invention I have illus trated the same as embodied ina portable platform scale in which guides are mounted upon the platformon opposite sides of the point of suspension so as to provide for theplacing of any heavy articles thereon, such as loaded trucks, etc. Theseguides are provided with means for adjusting the position of the same sothat if the two loads are unequal in weight, the same may be adjustedafter being placed upon the platform so as to balance one another whenthe platform is raised.

Other objects of the invention will be obvious in connection with thedescription of the embodiment shown in the accompanying drawings.

Figure 1 is a perspective view of a portable raising beam scale,embodying the invention. Fig. 2 is an enlarged perspective view of aportion of the platform.

The platform 1 is preferably in the form of a rectangular framesuspended at the center by means of a yoke 2, which in turn is carriedby a central beam 3. The weight 4 is arranged to besuspended from thescale beam 3 .by means of the chain 5 and the hook 6. The scale beam 3and its attached parts are suspended from a lever 7 which is pivotallymounted at 8 upon an upper cross bar 9 on the supporting frame. Thissupporting frame is provided with detachable end members 10 and 11,which are secured thereto by the braces 12 and 13 which are arranged tohook over suitable pins on the cross-bar 9 and thus provides a knockdown construction permitting the scale to be readily taken apart. At theouter end of the lever 7 a cable 1 1 is attached which in turn isarranged to be wound upon a suitable windlass 15 for raising the scalebeam and platform, as will be readily understood by reference to Fig. 1.An auxiliary lever 16 provided with a weight 17 is pivotally mounted atS and provided with ad justable connections 18 with the supporting lever7. The purpose of this auxiliary weighted lever is to counter-balancethe weight of the platform so that less power is required at thewindlass 15 to raise the same.

The platform 1 is provided with a pair of guides 19 and 20 which arepreferably in the form of parallel angular members slidably mountedtransversely upon the platform 1. As shown in the drawings these guidesare provided with rollers 21 and 22, respectively, so that the same maybe more readily moved. The means for moving or adjusting the position ofthese guides is clearly shown in Fig. 2 and comprises a threaded member23 attached to one of the guides in connection with which a screwthreaded shaft 2 1 is operated by means of sprocket 25 and chain 26,driven by the hand wheel'27.

A detachable connection 28 is provided between the two guides 19 and 20so that both of the same may be moved simultane ously or one alone maybe moved and it will thus be seen that when the loaded trucks or thearticles to be weighed are in position on the guides 19 and 20 that thesame may be adjusted in position upon the platform 1 so that if theweight of one exceeds that of the other they may be placed in such aposi tion as to balance one another relative to the point of suspensionof the platform, which condition it will be understood, is essential inorder to secure an accurate record of the weight.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention designed withoutdeparting from the scope of the appended claims, I intend that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative merely of an operativeembodiment of my invention and not in a limiting sense.

lVhat I claim is:

1. In a weighing device, in combination, a scale beam, a platformsuspended from said scale beam, two sets of guides slidably mounted uponsaid platform, a separable connection between said sets of guideswhereby one or both may be adjusted in position relative to the point ofsuspension of said platform, and means for adjusting the position ofsaid guides.

2. In a weighing device, in combination, a scale beam, a platformsuspended from said scale beam, two sets of guides mounted upon saidplatform each adapted to receive a load, means for sliding one of saidguides toward or away from the other of said guides to compensate forthe difference in weight of the respective loads.

3. In a weighing device, in combination, a scale beam, a platformsuspended from said scale beam, two sets of guides mounted upon saidplatform each adapted to receive a load, means for simultaneously movingboth of said guides on said platform to compensate for the difference inweight of the respective loads.

4. In a weighing device, in combination, a scale beam, a platformsuspended from said scale beam, two sets of guides mounted upon saidplatform each adapted to receive a load, means for moving one or both ofsaid guides on said platform to compensate for the difierence in weightof the respective loads.

5. In a weighing device, in combination, a scale beam, a platformsuspended from said scale beam, a plurality of guides on said platform,a threaded member on one of said guides, a screw threaded shaft passingthrough said threaded member, means for connecting said guides together,and means for rotating said threaded shaft to move said guides on saidplat-form.
